Indeterminate state of check box

CheckBox.State=CheckBoxStates.TriState;

Or is there some other way to do that?

Also is it possible to change the visual look of the checkbox as :

Yes. IsThreeState = true; See following (with examples)

Yeah... you can use a Nullable<bool>. Assuming you can override the Control somehow. But for a tri-state, I think the following should provide a good idea:

bool? = false 
bool? = true
bool? = null

So try: bool? TriState
